Description

Copper sheathing casting mould structure

Technical Field

The utility model relates to a copper sheathing casting field, in particular to grinding apparatus structure that copper sheathing casting was used belongs to copper sheathing production technical field.

Background

The copper bush is a common part on a bearing and a shaft sleeve, when the copper bush is produced by a centrifugal method, a cylindrical mould is generally connected on a rotary driving device, the axial direction of the cylinder is in the horizontal direction, a front baffle cover is fixed on a cylinder opening on the cylindrical mould, copper liquid is poured into the mould after the rotary driving device drives the mould to reach a certain rotating speed, the copper bush with two cylindrical sides is formed under the action of centrifugal force, and then a final product is obtained by machining, the method can be better applied when the outer peripheral surface of the copper bush is a cylindrical surface, but in the production of the copper bush, two ends of a variety of copper bushes 8 are respectively provided with an outward extending flat edge 9 (I-shaped copper bush), as shown in figure 5, the copper bush in the form is produced into a casting with a cylindrical outer peripheral part by adopting a cylindrical mould line in the traditional production process, and then the middle part is formed into an I-shaped product by machining on a machine tool, this approach has the following drawbacks: firstly, the subsequent machining amount is large, and the part needing to be removed occupies a large volume; secondly, because the amount of removal is great in machining, the proportion of the volume of the finally obtained actual workpiece product to the volume of the whole casting piece is small, so that the casting efficiency is low, and the casting energy consumption of the unit workpiece is high.

Disclosure of Invention

An object of the utility model is to overcome the above-mentioned problem that exists in the casting of present copper sheathing, provide a copper sheathing casting mould structure.

In order to realize the purpose of the utility model, the following technical proposal is adopted: a copper bush casting die structure comprises an outer die and an inner die, wherein the outer die and the inner die are cylinders with bottoms, the inner die is sleeved in a cylinder of the outer die and formed by splicing two semicircular cylinders, the two semicircular cylinders with bottoms are attached together along the radial direction to form a cylinder of the inner die, a section of conical inclined plane I which expands outwards in the radial direction is arranged at the axial outer end of the inner die, the outer part of the conical inclined plane I is connected with a cylindrical surface I, a section of conical inclined plane II which expands outwards in the radial direction is arranged near the bottom surface, a cylindrical surface II is arranged between the conical inner inclined plane and the bottom surface, and after the inner die is sleeved in the outer die, the inner die is flush with the outer ring of the outer die; further, the method comprises the following steps of; the binding surfaces of the two semicircular cylinders are provided with mutually matched bulges and grooves; further, the method comprises the following steps of; the binding surfaces of the two semicircular cylinders are provided with mutually matched bulges and grooves which are continuously arranged along the length direction of the binding surfaces, and the bulges and the grooves are in V shapes.

The utility model discloses an actively beneficial technological effect lies in: by adopting the mould, the outwards extending flat edges at the two ends can be basically formed in casting, the subsequent machining cutting amount is greatly reduced, the machining cutting amount of the mould structure can be reduced by more than 85% compared with that of the traditional production process, the volume ratio of the final product to the initial casting is greatly improved, and the energy consumption of the unit casting is obviously reduced.
